• Using this device, you can check instantaneously the seeing value in arc seconds at your specific location
• Shows instant seeing value, light input and 1 minute moving average
• Separate sensor can be placed next to the entrance pupil of your instrument
• Runs on battery or USB

• Holds all all Zeiss devices - with 68mm thread (with 19mm optical height)
• Keeps all Vixen Optics - with 60mm thread on the focus tube (with 24mm optical height)
• Keeps all Astrophysics refractors with 2.7 "thread (with 13mm optical height)
• Keeps all Skywatcher- / Celestron refractors, all Synta optics - with 56mm thread on 2 "eyepiece holder (with 31mm optical height)

• Baader H-alpha Narrowband Filter – Precision Grade
• 6.5 nm FWHM, recommended for optical systems from > f/3.4
• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
• Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
• Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies

We explicitly warn against observing the sun with a DeepSky 6.5 nm (equivalent to 65 Ångstroem) H-alpha narrowband filter, specialized solar chromosphere and prominence filters from SolarSpectrum start at 0.8 Ångstroem. Photographic experiments with a camera are theoretically possible, but by no means observe the sun with naked eyes – you endanger your eyesight!
